Graduate Statistics Topic 0 - MANU Directions: Complete this assignment in 500-750 words using the following information: A researcher randomly assigns 33 subjects to one of three groups. Group 1 receives technical dietary information interactively from an online website. Group 2 receives the same information from a nurse practitioner, while Group 3 receives the information from a video made by the same nurse practitioner. The researcher looked at three different ratings of the presentation: difficulty, usefulness, and importance to determine if there is a difference in the modes of presentation. In particular, the researcher is interested in whether the interactive website is superior because that is the most cost-effective way of delivering the information.
